Use QuickTime Player to create a video wall

Have you ever wanted to create a “video wall” on your Mac—that is, fill your screen with a bunch of different video clips, all playing at the same time? I can’t say that this is something I’ve ever needed to do myself, but it does make for an excellent demo. While I’ve seen commercial rigs that do this with a mix of separate monitors and associated hardware and software, I’ve not seen anything like today’s tip, which uses QuickTime Player to create a do-it-yourself video wall on your monitor.

Often here on the Mac OS X Hints blog, I’ll present a tip that includes an AppleScript, and walk through the steps the script takes to do what it does. Other times, though, the script is longer and more complex, and such an explanation would make the column just slightly shorter than Tolstoy’s “War and Peace.” Such is the case with this video wall hint—I’m not going to explain the code, just present it for download, and let you know that it worked well in my testing.

After you download the linked file, expand it, and it should be ready to use—you might drag it onto the Finder’s toolbar or sidebar to make it easier to access, and possibly paste a custom icon onto it to make it easier to see, but it’s ready to go as is. To use the new application you created, select a number of video clips and drag and drop them onto your program’s icon.

QuickTime Player will launch, and start opening the dropped clips. The clips will be sized and arranged to take best advantage of your screen space, and all the clips will play at the same time (in loop mode, so they’ll repeat). Just note that the more clips you drop, the longer it will take to open and arrange them. I tested this myself with about a dozen clips, and it worked as expected. I can’t say it’s something I’m going to use very often, but it is impressive to watch.
